O Notes
 1. Use a 10 : 1 probe for the oscilloscope.
 2. All the knob positions (settings) for the oscilloscopein the adjustment procedures are for when a 10 : 1 probe is used.
O Test Mode
 These models have a test mode so that the adjustment and checks required for service can be carried out easily. When
 these models are in test mode, the keys on the front panel work differently from normal. Adjustments and checks can be
 carried out by operating these keys with the correct procedure. For these models, all adjustments are carried out in test
 mode.
 When the test mode is set correctly, the display is different from vrhat it usually is when the power is turned
 If the display is still the same as usual, test mode has not been set correctly, so repeat Steps 1-2.

                                                         to its original position.
